"The utility of UAVs goes beyond delivery missions. Drones can also be used to physically evacuate patients. They can sit at a forward operating base or patrol house for weeks at a time. They never get tired or ‘out-of-hours’. Empty and en-route to target they are only machines and are disposable, they are risk free."
